JOHAN A. BRUDIN, OF NEW YORK, N. Y.

VALVE.

SPECIFICATION forming part of Letters Patent No. 393,536, dated November27,1888.

Application filed February 8,1888. Serial No. 263.330. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHAN A. BRUDIN, a citizen of the Republic ofSwitzerland, at present residing in New York, in the county and State ofNew York, have invented a new and Improved Valve, of which the followingis a full, clear, and exact description.

This invention relates to a novel form of valve which may be employed inmany ways, but which is designed more especially for use in connectionwith flasks of aerated waterssuch as are known in the trade as siphons--the invention consisting, essentially, of a pouchlike packing, aspring-pressed piston arranged in connection therewith, and a thumbpiecemounted to throw the piston against the tension of its spring, all aswill be hereinafter more fully described, and specifically pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in both the views.

Figure 1 is a central longitudinal sectional view of my improved form ofvalve, and Fig. 2 is a crosssectional view taken on line a: m of Fig. 1.

In the drawings, 10 represents the barrel or body of the valve withwhich communication is established by means of an inductionport, ll, andan eduction-port, 12. Just within the port 12 the inner defining wallsof the recess or chamber of the barrel 10 are inclined, as shown at 2,said inclined walls constituting the valve-seat.

The chamber within the barrel 10 consists of two compartments,of whichthe inner compartment,A,is of less diameter than the outer compartment,a shoulder, 3, being formed be tween the two compartments, whichshoulder serves as a support or rest for a flange, 4, that is formedupon a pouch-like packing, 5, the flange 4 being held to the shoulder 3by a washer, G, which washer is borne upon the inner edge of a threadedflange, 7, that is formed upon the cap 13, the walls of the largercompartment of the valvebarrel being threaded in order that they may beengaged by the thread of the flange 7.

The washer 6 is centrally apertured to provide for the passage of avalve-stem, 8, the plug or valve proper, which is shown at 14, beingsecured to that end of the stem which extends inward within thepouchlike packing 5, this valve being held against the end of the innerdefining wall of the packing by a spiral spring,15,which is mountedbetween the valve and the washer 6. The outer end of the stem 8 isheaded, and just within the head there is mounted a second washer, 9.

The walls of the valve barrel or body are apertured at a,and in flange 7there is formed an aperture, b, which, when the cap is turned home, willregister with the aperture a. A thumb-lever, 17, formed with abearing-finger, 16, is passed downward through the apertures a and b,thelever being mounted upon a pin, 18, whereby, if the thumb-lever bethrown in the direction of the arrow shown in connection therewith, thestem 8, and with it the valve l4,will be drawn back against the tensionof the spring 15, thus leaving the end of the pouch-like packing free tocollapse when subjected to any pressure from within the chamber A.

Having thusdescribed my invention, I claim as new and desire to secureby Letters Patent- '1. The combination, with a barrel formed with avalve-chamber and seat, of a flanged pouch-like packing, an aperturedwasher for holding the packing in place, a valve arranged within thepouch-like packing, and provided with a stem projecting through thewasher, a spring surrounding the valve-stem within the pouch-likepacking, and with its ends resting against the valve and washer, andmeans for moving the valve against the tension of the spring,substantially as described.

2. The combination, with the slotted barrel 10, provided with theinduction-port 11, the eduction-port 12, the valve seat 2, and theshoulder 3, of the flanged pouch-like packing 5, the apertured washer(5, for securing the pouch-like packing in place, the valve 14 in thepouch-like packing, and having its stem 8 projecting through theaperture of the washer and carrying on its end a washer, the spring 15,surrounding the valve stem in the pouch-like packing and abuttingagainst the valve and washer, and a thumb-lever pivoted in the slot ofthe barrel and provided with a finger engaging the washer carried by thevalve-stem, substantially as herein shown and described.
